Phone rings - no one at the other end - then hangs up. Twice a day for last several days...

Commonwealth collection trying to collect $8000 that by brother owes from his crack days.

Car warranty telemarketer. If you have time, waste their time by stringing them along with incorrect information. Seem to be enthusiastic, ask them to repeat a lot, and like I say, give wrong info.

Wasting their time is the way to get back at them....
